Description

[Technical Field]

[0001] The present invention relates to an exhaust hood, and more particularly to an exhaust hood used in the production line of an instant noodle or steamed noodle factory. [Background technology]

[0002] Conventionally, in production lines in factories for instant noodles or steamed noodles, as shown in Patent Document 1, an exhaust hood is provided on a conveyor that transports noodle strands to exhaust steam and the like. For example, as shown in FIG. 5 of this specification, when the conveyor 200 rises at an angle of 35 degrees and then extends so as to become horizontal, the exhaust hood 100 disposed above the conveyor 200 is also integrally formed at a corresponding angle, specifically, so as to rise at an angle of 35 degrees and then become horizontal. However, this required a new exhaust hood every time the conveyor's lift angle was changed, which posed problems such as the cost of replacing the exhaust hood, the effort required for the replacement work, and the disposal of old exhaust hoods.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-017167 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0004] The purpose of this invention is to provide an exhaust hood that can easily accommodate changes in the angle of the conveyor, especially in production lines in factories that produce instant noodles, etc. [Means for solving the problem]

[0005] The exhaust hood of the present invention comprises a pair of side hoods each having an intake port, and a central hood which is separate from the pair of side hoods and is sandwiched between the pair of side hoods to connect to a duct, and is characterized in that the attachment angle of the pair of side hoods relative to the central hood is adjustable.

[0006] This device allows the mounting angle of a pair of side hoods to be adjusted relative to the separate central hood, so that in factory production lines for instant noodles, etc., the pair of side hoods can be mounted so that they follow the angle of the conveyor, with the central hood as the axis. This means that when changing the angle of the conveyor, it is only necessary to change the mounting angle of the pair of side hoods around the central hood, eliminating the need to discard the exhaust hood that was in use before the angle change, and saving on replacement costs, etc.

[0007] More specifically, the pair of side hoods and the central hood may have hollow portions formed therein, the upper opening of the central hood may be connected to a duct, and the side openings on both the left and right sides of the central hood may be fitted into the pair of side hoods, respectively. Preferably, the pair of side hoods have fitting portions on the inside of their upper portions that fit with the central hood, and the air inlets are formed on the inside of their lower portions. [Effects of the Invention]

[0008] According to this invention, in a factory production line for instant noodles, etc., the mounting angle of a pair of side hoods relative to the central hood can be adjusted to match the angle of the conveyor, so that an exhaust hood can be easily provided that matches the angle of the conveyor when changing the angle of the conveyor or setting up a new production line. [Brief explanation of the drawings]

[0009] [Figure 1] The layout of the exhaust hood and conveyor is shown, with (a) being a plan view and (b) being a side view. [Figure 2] The structure of the exhaust hood is shown, with (a) being an exploded view and (b) being a cross-sectional view to explain the steam flow. [Figure 3] The structure of the side hood is shown, with (a) being a front view, (b) being a plan view, (c) being a right side view, and (d) being a left side view. [Figure 4]1A and 1B show plan views of an exhaust hood according to a first embodiment and a second embodiment, respectively. [Figure 5] FIG. 1 shows a side view of a conventional exhaust hood and conveyor.

[0010] An example of the structure of the exhaust hood according to the present invention will be described below with reference to the drawings, but the present invention is not limited to this embodiment.

[0011] In a production line in a factory for instant noodles or the like, an exhaust hood 1 is disposed above a conveyor 2 that transports noodle strings, as shown in FIG. 1, to exhaust steam and the like. The exhaust hood 1 is shown in FIG. 1(a) as a plan view, FIG. 1(b) as a side view, FIG. 2(a) as an exploded view seen from the front, and FIG. 2(b) as a front cross-sectional view. The exhaust hood 1 has a pair of side hoods 10, 20 and a central hood 30 that is separate from the side hoods and is sandwiched between the pair of side hoods 10, 20 and connected to the duct 3, and the attachment angle of the pair of side hoods 10, 20 relative to the central hood 30 is adjustable.

[0012] FIG. 3 shows the structure of the side hoods 10 and 20. The pair of side hoods 10, 20 are each box-shaped with a hollow space formed inside, and in this embodiment, as shown in Figure 3(c), the lower parts 11, 21 are an example of an inverted T-shape in side view, with the front-to-back width of the lower parts 11, 21 being greater than that of the upper parts 12, 22. Inlets 13, 23 for steam and the like are formed in the lower parts 11, 21 of the side hoods. In this embodiment, suction ports 13, 23 are provided on the inside of the lower portions 11, 21 so as to open and extend in the front-rear direction along the shape of the lower portions. The upper portions 12, 22 of the side hoods have mating portions 14, 24 that mate with the central hood, and in this embodiment, approximately cylindrical mating portions 14, 24 protrude from the inside of the upper portions to mate with side openings 31, 32 on both the left and right sides of the central hood 30, which will be described later.

[0013] The central hood 30 also has an internal cavity. As shown in FIG. 2(a), this embodiment has an inverted T-shaped cylinder shape when viewed from the front, with side openings 31 and 32 on both the left and right sides opening through in the left-right direction, and an upper opening 33 connected to the duct 3. The side openings 31, 32 of the central hood are fitted with the fitting portions 14, 24 of the pair of side hoods 10, 20, respectively. In this case, by fitting the side openings 31, 32 into the fitting portions 14, 24, or by fitting the fitting portions 14, 24 into the side openings 31, 32, the attachment angle of the side hoods, particularly the angle at which the lower portions 11, 21 of the side hoods extend, is fixed around the central hood 30 as an axis. Alternatively, as shown in the plan view of the exhaust hood 1 in Figure 4(a), after adjusting the mounting angle of the pair of side hoods 10, 20 relative to the central hood 30, the lower parts 11, 21 of the pair of side hoods and / or the upper parts 12, 22 of the pair of side hoods may be fixed together and their positioning strengthened using removable fixing auxiliary members 41, 42. There is no particular limitation on the number or structure of the auxiliary fixing members, as long as they are relatively easy to remove.

[0014] The exhaust hood 1 may have a ceiling panel 40 as shown in FIG. 2 so that steam and the like can be more easily drawn to the inlets 13, 23. In this embodiment, the pair of side hoods 10, 20 are provided with ribs 15, 25 that protrude inward above the suction ports 13, 23, and a ceiling plate 40 can be placed and fixed on the pair of ribs 15, 25. As a result, as shown in the cross-sectional view of Figure 2(b), steam flowing toward the ceiling panel 40 passes through the side hoods 10 and 20 from the intake ports 13 and 23, and is then exhausted through the central hood 30 connected to the side hoods and the duct 3.

[0015] Conventionally, as shown in FIG. 5, an exhaust hood 100 disposed above a conveyor 200 has been integrally formed so as to correspond to the angle of the conveyor 200. For example, the exhaust hood 100 through which steam passes is U-shaped when viewed from the front, with a central portion connected to the duct 300 and side portions hanging down from it, and these are attached together by welding or the like. The shape of the side portions, particularly the lower edges of the side portions, are processed and formed to follow the angle of the conveyor relative to the floor, thereby manufacturing an exhaust hood 100 that corresponds to the angle of the conveyor. However, since the exhaust hood is machined and formed at a predetermined angle, it is not possible to easily accommodate changes to the angle of the conveyor after manufacture. In contrast, in the present invention, the central hood 30 and the pair of side hoods 10, 20 are separate entities, and the mounting angle of the side hoods is adjustable, making it easy to accommodate changes to the conveyor angle when changing the conveyor angle or setting up a new production line. For example, if the conveyor has a large width, the exhaust hood 1, which is H-shaped in plan view as shown in Figure 4(b), can easily accommodate the width of the conveyor by using a central hood 30 that extends long in the left-right direction, just like the conveyor. In addition, in the case of a conveyor 2 that extends long in the front-rear direction as shown in FIG. Furthermore, a curtain (for example, a vinyl curtain) 50 may be attached so as to hang down from the exhaust hood 1 toward the conveyor 2, which makes it easier to attract steam.
